No amount of training or seminars will ever make you a salesman. Ever wonder why there are so few extremely wealthy salesmen in the world? Well, it is simple - for one they were in the right place at the right time, spotted an opportunity and took it. Two is that they became wealthier by selling you their sales training with the belief that they could make you become them (which is a complete lie)
Let's take Jordan Belford for example, The wolf of wall street. He made it big selling penny shares. Selling Normal Shares made you 1% comm back then, while penny shares made 50%. Lucky for Belford he had Wall Street tactics, coupled with his electrifying personality, and knew what to say to lure in the 'big fish' and he capitalized on that opportunity.
Yes, they can teach you what and how to speak, but a salesman is born with a passion and a desire that is unmatched when it comes to attaining wealth.
Belford cannot teach you how to sell, he can teach you what to do, but that will mean nothing to you when you have the door slammed in your face time and time again. That will mean nothing when the customer has an objection that Belford did not teach you how to counter. If you don't have that captivating aura then you can read them the manual and never sell a thing. If you don't have the vibe about you people will not buy from you when someone like Jordan Belford or Grant Cardone comes along with their pitch.
Their training will make you more effective when it comes to script selling, but you will never make the kind of money they have because you wont be able to sell beyond that script if you are not a salesman. Stop believing that buying their training will make you rich like them, you just making them richer because they have just sold something to you without you even realising it.
There is plenty of useful Youtube video's on how to sell that are free and can teach you as much as their training in 100th of the time.
